摘　　要：文章阐述了地下水位的基本定义,分析了影响地下水位测试结果的主要因素,在此基础上提出了一种能够在考虑土层固结影响且能保证水位管与大气不连通的情况下较为简便地获得相对准确的地下水位高程的测试技术,并给出了修正方法。目前该法已成功应用于连云港盛虹炼化一体化项目一期工程(第2标段)地基预处理项目,可真实地测出地下水位。The main factors which affecting the test results of groundwater level were analyzed.A new testing technology and method which considering the effect of soil consolidation was proposed on this basis,which can simply get accurate groundwater level elevation under the conditions of ensuring disconnection between water level pipe and atmosphere,and the correction method was given.At present,this method is successfully used in the foundation pretreatment of refining and chemical integration project(No.2)which belongs to the first phase of Lianyungang Shenghong,so this new instrument is reliable to measure the groundwater level.
